how to set restraint when panning mc left and right

[Ling Nightsky]

Please help me.
I have scripted for a movieclip to pan left and right according to the mouse but i want it to stop when the side of the movieclip reached the side of the mask. That is i don't want to see the background behind, i want the movieclip to stop panning exactly before the bg reveals. Please review my source file and tell me what's wrong. thanx

i think this is the part that went wrong

myClip = movie1;
if (myClip._x< -119) {
stopDrag();
} else {
startDrag("drag", true);
}
xposition = getProperty("movie1", _x);
movie1._x += (xposition+drag._x)/((100-speed)*-1);
movie1._x += (xposition+drag._x)/((100-speed)*-1)+num;
movie1._x += (xposition+drag._x)/((100-speed)*-1)-num;

but, id do it like this:

Have free frames.
FIRST FRAME
if so you need to set somes stoppers before the loop starts to say when the mc should stop and where the centre (where it starts) is.

center = 250;
reelPos = mcname._x;
leftStop = -250;
rightStop = 500;

SECOND FRAME

Put in the code the calculates where the mc is and how far from the mouse it is. And finally moves it appropriatly.

if (_ymouse>1) {
photoSpeed = (_xmouse-center)/10;
photoPos = Math.round (photoPos+photoSpeed);


if (photoPos<leftStop) {
photoPos = leftStop;
}
if (photoPos>rightStop) {
photoPos = rightStop;
}
photo._x = photoPos;
}

THIRD FRAME
Loop it! so it keeps calculating and moving the mc. (label frame two 'loop')

gotoAndPlay ("loop");

sorry about the spelling and i hope this is what you wanted.
